When land near Dravosburg catches your eye, the West Mifflin GIS map shows the outline, the owner of record and a parcel ID. In this West Mifflin guide: which viewer to open, how to search it, and what to double-check with records.
Finding a lot on the West Mifflin GIS map
Near Dravosburg, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The free map to start with
Property in and around Port Vue can be looked up on the Allegheny County ArcGIS parcel map, free to use and open without a login. For a home near Port Vue, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Port Vue, write down the parcel ID from that panel; each records desk in the county uses it to find the file.
Reading the legal description
Rural deeds near Munhall are often described by metes and bounds, listing bearings, distances and landmarks. Platted lots around Glassport usually use lot and block from a recorded plat instead, making them easier to find. Write down the legal description for the tract near Dravosburg before you request a deed or survey.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Port Vue, but coverage can be spotty out of town. A saved image of the lot near Glassport and its lines is a good backup.
Limits of the parcel data
The acreage figure is an estimate; just a licensed surveyor establishes the real lines for a parcel near Dravosburg. For property near West Homestead, records update in batches, so a deed recorded last month might lag behind.
Offices that can help
If the acreage or value on a parcel near Baldwin looks off belong with the county assessment office, the office behind the parcel record. Zoning, permits and septic questions near Dravosburg are for the local planning and health departments, town or county, depending on location.
